Abstract: Abstract of the Disclosure A process for cooling a polymerization reaction of compounds in dispersion and/or solution in a reactor in which the cooling is effected by evaporation of one or more liquids contained in the reactor, condensation of the vapour in a reflux condenser and recycle of the condensed vapour into the reactor, together with the use of a controllable flow of coolant which is introduced into the reflux condenser jacket.  The quantity of heat released on condensation is utilized as the control variable for controlling the cool-ant inflow to the reflux condenser.  Thus, the control system can function virtually without a time lag.

Abstract: ABSTRACT            An improvement in a process for preparing a laminate consisting of fluorocarbon copolymer sheet of 5 or more mil thickness and a fabric is disclosed. The improvement is using a thin sheet of a fluorocarbon copolymer having a specific melt viscosity low enough to enable the copolymer to wet and penetrate the fabric at fabrication temperatures as an interlayer between the fabric and thick fluorocarbon copolymer sheet and then integrally bonding the laminate by means of heat and pressure. The use of the interlayer increases the level of adhesion between the thick sheet and the fabric.

Abstract: ABSTRACT OF THE DISCLOSURE     A vertically-adjustable drafting table having a base with a pair of telescoping support columns defining an open area between the columns suitable for accommodating any of a variety of modular storage unit combinations is disclosed.          Each column is composed of telescoping upper and lower sections, the lower sections being secured to a horizontal beam and the upper sections being attached to a table top.  A cable extends in an endless loop through the beam and upwardly into each of the columns.  Guides in the form of pulleys are disposed within each of the columns and within the beam for guiding movement of the loop of cable, and sections of those stretches of cable extending upwardly into the columns are secured to the upper column sections.  A spring disposed within the base urges the loop of cable in one direction to counterbalance the combined weight of the upper column sections and the table top.  In one embodiment, the pulleys within the columns are adjustably mounted upon stalks disposed within the columns, thereby permitting adjustment of the tension of the cable loop.

Abstract: ABSTRACT OF THE DISCLOSURE      A process for the production of pile-surfaced material which comprises the steps of interposing a thermoplastic material between a backing and a sub-stantially smooth heated surface, holding the backing against the thermoplastic material so that bonding of the backing to the thermoplastic material and adhesion of the thermoplastic material to the heated surface occurs, parting the thermoplastic material from the heated surface over a bar so that fibrils are drawn out from the thermoplastic material between the backing and the heated surface, and hardening the fibrils as they are drawn out at least in part by a stream of cooling fluid directed at the side distant from the heated surface through the bar.    The present process seeks to improve both the uniformity of pile produced by this type of process, to allow uniform piles to be produced at higher speeds than before possible and to provide a versatile process which is readily adaptable to produce varying types of pile.
